July’s LAM looks at the long-needed rehabilitation of Babi Yar Park, a memorial ground in Denver dedicated to the lives lost in Kiev, Ukraine, during the Holocaust, by Tina Bishop of Mundus Bishop; a rethinking of Chavis Park in Raleigh, North Carolina, by Skeo Solutions, which embraces the park’s African American heritage through public engagement; and the ground-to-crown planting of the One Central Park high-rise in Sydney, designed by Ateliers Jean Nouvel, with Aspect | Oculus and Jeppe Aagaard Andersen, where sprawling green balconies make what is said to be the tallest vertical garden in the world.

In this month’s departments, the Milan Expo 2015 centered on food sustainability seems to draw controversy from every angle; Molly Meyer is leading the charge for affordable, simpler, and greater biodiversity in green roofs; and nature reclaims lands once lost from the demolition of two dams on the Elwha River in Washington State. In The Back, an exhibit at the Smithsonian National Museum of Natural History immerses visitors in the beauty of Iceland through sight and sound. All this plus our regular Now, Species,Goods, and Books columns.
